This feature film is set in 1645 at the end of the English Civil War. The rebel New Model Army has defeated the Royalist forces of King Charles I and Lord Thomas Fairfax and Oliver Cromwell emerge as heroes. Now the pair seeks to reform the crown and execute the King which leads to civil unrest.

The production visited Kent to film at Penshurst Place where the interiors doubled as Cromwell’s living quarters. Dover Castle doubled as The Tower of London and the castle’s tunnels were also used in the scene where Fairfax and Cromwell search for the king’s missing gold.
